Fuck Or Die With Iida But This Time I Write It With My Full Pussy

🫶

thinking about how katsuki is obsessed with you when he's drunk! it doesn't happen very often due to how health conscious that man is, but when he is drunk, he can't keep his eyes—or hands, off of you. and it's not even sexual, the way he gently rests his hand on your lower back, or how he drapes his long limbs and loose body around you. he presses little kisses to your head every so often and drags you to sit on his lap in the middle of conversations, his focus always on you.

if you get up to get another drink, he's close behind, hands gently resting on your hips as you lean against the bar to talk to the bartender. and if you’re giggling at little too much over what the bartender is saying, katsuki gets a little pouty and will gently tug on a lock of your hair, letting you know that he’s still right behind you.

Imagine Hawks confiding in Endeavor that he’s been sleeping with one of the League members and Endeavor is like “Whatever you have to do to get information, do it.” and then later realizes that he was encouraging Hawks to go fuck his son 💀💀💀

a/n: word vomited this out in less than 24 hrs

He’s praying you don’t pick up.

“Bakugou?” You sound annoyed, a little suspicious even.

He never calls you.

“Ace.” You hate that nickname, but the thought of saying your actual name in the desperate growl that is his voice right now makes his head spin. “I need - fuck - are you home right now?”

Sex quirks are a dime a dozen these days. He’s been hit with a few before, simple one that are usually pretty easy to shake. (He still hates the premature ejaculate memory, though, coming home with his boxers stiff and an image of you spread out on his bed playing like a film in his head. He hadn't been able to look you in the eyes for weeks.)

He’s never been hit with one as strong as this. The second the mist hit his nostrils he was huffing up the scent of vanilla and citrus and strong black coffee, just the way you like it, before he realized what was happening, the villain ripping down the street in the opposite direction while arousal hit him like a truck.

Bakugou's practically doubled over talking to you now, the ache in his dick throbbing in time with his fucking heartbeat.

“Yeah, I’m home.” Even annoyed you sound like heaven. “What’s going on? You don’t sound like yourself.”

He barks out a laugh, and before he knows it, he's telling you the truth. “Got hit with a sex quirk. A big one.”

Your breath bitches slightly on the other line. He’s pretty sure his cock jumps at the sound.

“And I - " need you right fucking now - “fuck - I can’t call anyone else.”

It has to be you. He’s got women he could call, sure, anyone who might want to get into a pro hero’s pants, but it has to be you for a reason he doesn’t want to look at too closely.

You’re silent for a beat, before you say, “Send me a pin. I’ll come get you.”

He hated you at first. Always talking his ear off about every fucking thing, bringing up articles that remind you of cases you're covering—it was like living with Deku dialed up to 11.

But what he hated even worse was when you stopped talking. When you realized he wasn’t actually gonna come around and be nice to you, when you figured out, oh fuck, he’s actually just an angry prick, and left him alone.

One day he could count on constant chatter when he was back from patrol, the next, nothing at all. You even switched up your schedule so he barely saw you, a fact he didn’t tell his court-ordered therapist because he was supposed to be getting better at being around other people, not worse.

He hates remembering this now with his dick hard as steel and weeping from the tip like he’s fucking 15. The alley is secluded, thank fuck, so no one can see him shaking and groaning, forearms braced on the wall in front of him, head hanging down like a panting dog. He can barely move; every brush of his pants against his erection like a live wire to the brain.

By the time you pull up—five minutes, forty six seconds later, he counted—he’s so frayed and tense that the minute he sees your face, he shouts, “Took you fucking long enough."

Your face shutters closed the way it always does around him, and he wants to fucking die.

“Fuck, Ace, I’m sorry - it’s just, I’m fucking miserable right now - "

“Why did you call me, Katsuki?”

It’s a mistake to look you in the eye. His restraint is a razor’s edge at this point, and seeing your beautiful face is too much. You've always been pretty, but the light shining on your soft hair is convincing him he can write fucking poetry all of a sudden.

“You know why,” he grits out.

You step forward, vanilla and citrus and coffee flooding his nose.

“No, I don’t. You act like you fucking hate me half the time and ignore me the rest.” You scrape a hand across your face in frustration. “And then you call me sounding like that. Why wouldn't I be confused?"

“I want you.” It’s out of his mouth in a flash, and he knows it’s the right thing to say by the way your shoulders relax. “I’m a fucking asshole, I know it. I’m not good at feelings, baby, I'm sorry, but I want you so fucking bad it’s like I could break my teeth over it. It has to be you, Ace, fuck, I’m sorry, it can’t be anyone else - "

You shut him up your mouth, your lips locking into his as both of your noses bump against each other. He doesn’t care; he just needs you as close to him as he can get you. It’s better than anything he imagined, finally touching you, finally giving in to the attraction that’s dogged him ever since you walked into his life.

You taste like coffee and a little bit of that strawberry lip gloss he loves so much. He licks into the seam of your mouth and relishes the shiver that goes through your body.

“Like that, baby?” He breaks away, nosing at your jaw, nipping at the juncture of your throat. That makes you gasp. “You smell so fucking good here.” He jerks his hips, hisses through his teeth as his cock jumps in his pants, pulsing with need.

“Let me,” he hears you say, and you’re tugging his pants open to get your hand around him. The second your fingers wrap around him his eyes roll up in his head. He could cum just from this, he realizes.

“Of course you’d have a pretty dick,” you say with a look of annoyance, and he’s not entirely sure what to say to that besides puff up his chest. You laugh, and it’s almost fond, and goddammit he wants you more than he’s ever wanted anything else -

With a growl, he pulls your hand away and backs you up against the wall, peppering kisses down your neck. The whines he’s pulling from your mouth is making everything in his life worth it. He’d fight a thousand fucking villains if it meant this, fingering the seam of your panties under your little skirt as you cry out for more.

“Wear this for me?”

“Like fucking hell I did,” you retort.

“Sure thing, princess.” He runs the pad of two fingers over the soaking wet seam of your panties. A feral grin passes over his face as your thighs tremble and press together. “This just happened to you all on your own?”

He roughly pulls your panties to the side to gather up the slick at your entrance, pushing your hips apart and settling himself between them.

“You’ve gotta come first, pretty girl.” You like when he calls you pet names; he’s been watching the way your skin breaks down out in goosebumps each time. It’s a like a drug being this close to you, making you feel this good. “The second I’m inside ya I’m gonna blow my fucking load so be good and come for me, yeah?”

The rough material of his fingerless gloves rubs against your clit as he stuffs two fingers in your pussy. Your little hole sucks him in greedily as you whine and buck against him.

“Harder, Kats, please - you won’t fucking break me - "

He adds another finger to stretch you out, keeping his palm rocking against your pubic bone with every grind. You’re fluttering around his fingers, whimpers echoing off the walls in the alley.

“That’s it, baby, there you go. Fuck, yeah, you like me stuffing this pretty pussy full?” You dig your nails into his scalp as you hold onto him for dear life, whimpers ratcheting up to moans and cut-off screams as he starts to feel your cunt clamp down hard on him.

You moan his name against his neck as you cum. “Just needed to think about me stuffing you full?” He can’t help but smirk, which quickly turns into a hissing groan when your hand finds him again and positions him right at your core.

“I could say the same for you,” you smirk, rolling your hips and coating the head of his cock in the slick of your orgasm. He chokes on his spit, bracing one forearm on the wall behind you, his free hand stilling your hips in place.

“Lift me up,” you pout.

“Didn’t know you were bossy.”

“Didn’t think you would like it,” you shoot back, rolling down onto his cock and taking an inch of him inside you. “This position’s better, isn’t it?”

“Of course it is, you devil woman.” He can barely think. “Baby, I don’t - god fucking damn it - I don’t have any - "

“I’m on birth control and I’m clean.”

“Same. Clean, too, I mean.” He’s rambling. He never rambles. “I’ve got my check-up stats in my phone if you’d like to see them.”

You laugh, and it’s the sweetest sound he’s ever heard in his entire life.

“Can I kiss you?”

It takes him aback, but he’s been dying to know what you taste like since he met you, honestly.

“Yeah, pretty girl. You can kiss me.” He nips at your mouth and laughs at your pout when he pulls away. “Let me get all the way inside ya though first, huh?”

He feeds you his dick inch by inch, clenching his teeth at the way you squirm and plead for more. You’re slippery and warm, your cunt making obscene squelching noises with every rock of his hips.

With one final thrust, he’s seated up to the hilt, balls slapping against the meat of your thighs and ass.

“So fucking perfect,” he moans in your ear. “All for me - just for me, isn’t that right, Ace?”

Your head jerks up and down in affirmation.

“Say it, pretty girl. Say you’re fucking mine. Tell me how much you like my dick getting this pussy nice and tight. Bet I can get her to scream again, huh?”

He pinches your clit between two fingers. You jerk in his arms.

“Close, princess? Like it a little mean?”

He rocks his his up so he’s dragging the head of his cock across your g spot, over and over. Your eyes roll back in your head and your breathing gets shallower, shorter.

“Please please don’t fucking stop, ohmygodohmygod feels so fucking good, Kats- "

Your pussy clamps down on him like a vice and all rhythm flies out the window. He grabs the meat of your hips and fucks up into you roughly, shooting thick ropes of cum against your cervix.

The creamy sticky ring at the base of his cock when he pulls out is probably the hottest thing he’s ever seen in his life.

He looks up at you, sees the appreciative gleam in your eye. You're turned on by that, too.

“Can we do this again when we’re home?” he asks. “Maybe after I’ve made you dinner?”

The smile you return is like the sun. “We better.”

izuku nervously walks into their kitchen one late evening after katsuki just got home from his 12 hour shift.

usually he's all over katsuki with kisses and an excited, 'welcome home kacchan!' so the blond automatically clocks the change and knows something's up.

turning towards the raven haired menace, katsuki crosses his arms in front of his chest to look like he's in control of the situation and lifts an expectant eyebrow. 'whats up, zuku?'

theres something he has hiding behind his back and katsuki gets a weird flash back to the time izuku got him to try a clay face mask.

he did the exact same thing he's doing now, he flashed his sweetest smile and listed all the health benefits and showed off his own smooth freckled skin as an example. it was a very convincing example.

katsuki bitched and complained at first but now, as long as izuku is the one putting it on him, it's been a nightly ritual since that day 2 years ago.

izuku nibbles on his lip and finally looks up at him. 'i-i made kacchan something.'

'ok..?' izuku started knitting awhile back and while he's slowly and surely getting the hang of it, he still hasn't perfected it yet. but bakugou knows he'll get there, it's only been a short amount of time and he's able to make small things like beanies or scarves.

'and it came out... alright? i probably shouldn't have tried something so complicated this early on but i wanted kacchan to have a dynamite theme christmas present no one else has and ever since your merch blew up i know that's basically not possible and I already made you so many beanies and scarfs so of course I couldn't make you even more beanies and scarves so-'

'show me it.' katsuki demands, he hasn't moved and he hasn't said much but the intensity in his voice shows izuku that the blond is excited.

so flashing a hopeful smile, izuku brings it out from behind his back and-

well it's definitely not perfect. and it's kinda very ugly. in that ugly christmas sweater kinda way that everyone actually kinda likes anyway.

'hm.'

🥦🥦🥦

they're at a christmas party with all of their friends and family.

and if anyone tries to say anything bad at all about the sweater katsuki's wearing, he flashes them a threatening eye that dares them to continue. it might not be the explosive anger he used to express but now it's silent, deadly and even more terrifying because well.

because grape juice tried, grape juice continued, he said something like- 'deku maybe you shouldn't be showing off the things you make that clearly shows you're still a beginner?' and now he's been punched, kicked out of the party and everyone wishes they could permanently throw him out of the group chat for a second, third, fourth, hundredth time.

after shaking out his fist, katsuki makes sure his sweater didn't get any grape residue on it and tugs izuku into his chest to give him a soft reverent kiss on the top of his head.

that he's currently shaking because holy all might, kacchan didn't have to do all of that.

'denki why do you still invite him to these things??' kiri asks.

'deku can you make me one too pretty please with a cherry on top? I'll buy you breakfast and lunch for a whole year!'

'oh! ok, yeah definitely!'

In yandere DabiHawks poly fics, reader is always clinging to Hawks.. I mean it's understandable. Hawks is friendlier, more open, outwardly affectionate and he's something Dabi struggles with... he's caring. But putting that aside, what if reader clung to Dabi instead 🤔

Dabi has always been intense, cerulean eyes that stare into your soul, big hands that like to grab at your throat- pull at your hair, the power to wield the brightest, bluest flames you've ever seen- and oh oh don't forget, he's not skinny and scrawny, he's packing quite a bit of muscle under his clothes. Everything about him screams, "STAY AWAY" and "RUN." But you obviously don't see the warning signs that are so blatantly there or you just really don't care, Dabi's not sure yet. Hawks despises it though, he's the hero, the good guy- he protects civilians from people like Dabi for fucks sake, so why do you cling to Dabi so fucking much, hm? Anytime they both come home Hawks hugs you and while you do reciprocate, it's half-assed. Giving him a loose hug before twisting out of his grip to run towards Dabi and jump on him, basically making out with him while Hawks has too watch and sneer. "Hey babydoll, you miss me, hm? You nod at him, wrapping your arms around his neck and kissing him, fisting at Dabis hair to keep him close. Dabi chuckles, slipping his tongue into your mouth as he opens his eyes to stare at Hawks, the ladder scoffs and walks away. At first, when Hawks and Dabi come to the agreement to share you and had taken you away, brought you to Hawks nice penthouse with a beautiful overlook of the city, Hawks was so sure you would favor him. It had taken you a little while to even warm up to them but for you to cling to Dabi when he was so mean to you at first pisses Hawks off and you make it so obvious you prefer Dabi. You don't even kiss Hawks, just a peck before he leaves for work and then you're bouncing over to Dabi with a gleam in your eye, plopping down on his lap as Hawks leaves more irritated then before. Hawks couldn't even explain how many times he's come home from an exhausting day of hero work to see you riding Dabi, grinding down on his cock as you whine like a bitch in heat, screaming Dabis name, begging to cum on Dabis cock.. but no, no, never Hawks. The only reason you let him kiss you is because you're so cock drunk on Dabi that you don't notice. Head thrown back as you whine, eyes screwed shut tightly with your nails making pretty red lines on Dabis chest. That's one of the only times Hawks can kiss you and even then, Dabi still smirks in his face, cause he knows, he knows you don't really like Hawks and he uses that. Dabi will fuck you over the kitchen table, timing your orgasm to when Hawks walks through the door. Just for him to scowl as you scream for Dabi. For the months you've been here, Hawks has never fucked you by himself, Dabi is always in the room or even inside you. You don't make a fuss when Hawks makes out with your pussy only because Dabi has you occupied with his tongue in your mouth and a hand around your throat. "There you go baby, letting the little hero eat your pretty pussy, huh?" Hawks glances up at you from his place between your legs, you nod at Dabi, not looking away from him as you continue to kiss him, licking at his tongue. That. That shit pisses off Hawks, he's taking the time out of his day to make your pretty pussy cum for and you don't even look at him. That won't fly with Hawks and he makes sure you know that as he slaps your clit a couple times. It has you keening backwards, into Dabis chest, whining out as you attempt to arch away. "You disrespectful bitch, I'm eating your pussy, making you cum in my mouth and all you can say is Dabi.. are you fuckin serious slut?" He pushes himself up from his stomach, grabbing you by your throat to pull you towards him. "You're so far up his fucking ass you won't even kiss me, won't tell me you love me or even hug me.. but you'll do all that and more for that prick, won't you bitch?" You try to thrash around, reaching towards Dabi and whining for him but that just pisses Hawks off more. Hawks pulls you towards the edge of the bed and pins you down. "You'll learn to love me angel, I'll make sure of that."

My guess for redacted—Lady Nagant. She got to be reformed, saved from her past. She got to restart and be a new person.

And what do you (reader) get? Erased. You never existed. Your contributions are hidden in the back of the skeleton filled closet with the rest of the Commission's old sins.

It's not that you hate her, oh no. You think sometimes you're happy for her. And other times you just wish she would evaporate into nothingness. She might be one of the only people who really understands what you've been through and that is scarier than her triple digit kill count.

Love you and your writing 💞💓🫰

cw: assault mention

I dont think it was her. but I think she was the reason that reader never told anyone.

maybe they used to have a mentor/pupil relationship. reader was supposed to be her replacement one day, someone to clean up messes just like Lady Nagant. Hawks was always the commissions favorite, but she hoped. she hoped that she was Nagant's favorite.

its weeks after it happened. [redacted] has been hovering around the commission, 'accidentally' bumping into you over and over again. it's getting hard to force a smile, so you find yourself in Lady Nagant's wake, riding her coat tails for the security.

"He's been watching you," she points out the moment you two are alone.

You nod. She just sighs and goes back to her work, adjusting the sights on her rifle- the one that isn't attached to her.

"You shouldn't make a habit-" she says it low. "Of sleeping with married men. People will think you're a slut."

Your stomach revolts and your throat goes wet with acid. It takes a moment to swallow the feeling down and mirror Nagant. How does she know? Is it the look in his eye? Or has he told people that you were with him willingly?

"I didn't-," you mumble, cool as you can. "I think he-"

A deep breath does nothing to calm your racing heart. It feels like another betrayal from your own body, fighting against what you want-

"I think he raped me."

The sentence sits heavy between you, but Lady Nagant doesn't look up from her work.

"I think you learned a valuable lesson," she says. "All of these heroes are just as vile as anyone else."

She pulls the receiver back, then lets it click forward.

"It's your fault for being stupid enough to trust a man."

BY THE BOOK : MIDORIYA IZUKU X READER

SUMMARY: When your pro hero boyfriend comes home to find you studying, he suddenly takes a great interest in helping out. You find his methods... questionable. TAGS/WARNINGS: nsft, hysterical literature (reading out loud while sexually stimulated), pro hero deku, deku still has ofa, support tech grad student reader, slight intelligence kink, gn + afab reader, cunnilingus, established relationship, aged up characters, fluff (3k) NOTES: Hi guys! I have been in survival mode as of late and the writing has been slow going; my sincerest apologies for how long it’s taking me to burn down my @ficsforgaza backlog. But I finally had the time & energy on my hands this weekend to work on this one and I had such a blast!! I hope I’m not too rusty–and if I am, I hope you enjoy it as much as I loved writing it regardless lol. Love you and thank you always for your patience. Happy Holidays!!

Sometimes, you thought you could tell your boyfriend was near, even before you heard his key in the lock.

It was something to do with his power, you’d always suspected—as a support engineer unduly interested in other people’s capabilities, you’d spent hundreds of hours turning it over in your head. It was the unnatural immensity of other people’s powers, you thought, pulling and coiling just beneath the surface of Izuku’s skin. In close proximity, after prolonged use, its presence felt like a shiver up the back of your neck.

You felt the barest hint of it now, an unsettled feeling creeping into the marrow of your bones, and you sat up on the couch just as you heard the scratch of Izuku’s keys at the door.

One For All fit cleanly into Izuku’s own unwavering intensity somehow, like the last piece of his puzzle. Though one would certainly never think so looking at him as he spilled through the door, pink-cheeked from the cold, all bright eyes, sweetly angelic features, and a riot of wild green curls. He looked windswept from the biting winter breeze. He also looked too kind to be carrying the sort of power he did—too sweet and eager and lovely.

“Look what the wind blew in,” you grinned at him over the back of the couch, after assessing he was well. Your eyes tracked the sinuous movement of those broad shoulders as he yanked his mouthguard over his head, the flex and pull of his bicep as he hung it beside the door. He was moving without pause, no sign of injury or muscle strain , and his suit was intact. Ordinarily you didn’t mind if there was a bit of shredding about the abs as long as he came back to you whole and hale, but in the winter you didn’t like him wandering about risking the chance of frostbite.

Your heart fluttered when Izuku returned your smile with one of his own, so beautiful and bright, chasing away the cold he’d tracked in like a warm sliver of sun.

“Lots of small, easy fights today?” You guessed, judging from his intact suit but clear whiff of power about him.

Izuku scrubbed a hand through that riot of curls, exposing the reddened shell of a cold ear. “I only had to use blackwhip a couple of times,” he said as he shouldered the door closed behind him, the muscle of his thighs flexing enticingly as he stepped out of his boots.

You gestured at the pot of soup you’d left warming on the stove, and the veritable pile of crusty bread beside it. Warmth and carbs, exactly what you would have wanted if you were a pro hero fresh off a long day of patrolling in the snow.

Izuku’s eyes fixed on it with an obliging amount of interest, and he almost tripped over himself in the genkan in his haste to get to the kitchen. “I love you,” you heard him say, muffled through a mouthful of bread, heard the clatter of the silverware drawer and a bowl being placed on the counter.

You smiled and turned back to the book in your lap, a particularly dry, knotty text on robotic imitation learning that had had your eyes drifting closed for the better part of an hour. It was the last you’d need to get through for your Wearable Technologies graduate course, and something you were deeply interested in incorporating into your design practice. You could train a piece of equipment on how an individual pro hero moved and deployed their quirk, and use predictive modeling to deploy assistance functionalities within milliseconds if you got it right—such as immediate cooling in pro hero Shouto’s temperature vest the moment he ignited an arm.

The implementation was going to be so cool—but the theory was so mind numbing.

You felt the couch sink in beside your feet, and Izuku peered interestedly at the title in your lap.

“Introduction to Robotic Imitation Learning,” he echoed, and you could hear the note of excitement in his voice. You suppressed a fond smile, knowing he was already thinking through the same applications you had—he was just as much of a nerd as you were.

“Introduction to Snoozing and Napping,” you grumbled, turning back to your page. “There are only so many words on the Kalman filter framework a brain can handle before the human mind shuts itself down.”

Izuku hummed in interest around a spoonful of soup, propping himself up against your leg. The exterior of his suit was still cool from the outside, and he groaned with relief from the warmth of your skin, even as you hissed at the chill.

You knew he wanted you to go on, so you generalized for him. “It’s an algorithm used for robotic motion planning—you not only take measurements of the thing you want to model but you account for uncertainties to predict the probability that something is going to happen.”

Izuku nodded, taking another spoonful of soup, gesturing for you to go on.

You summoned up the willpower to explain joint probability distribution, pleased when Izuku easily managed to follow—he’d always been a quick study, especially of anything that could be employed in the service of heroics. You’d long thought if he hadn’t been gifted his quirk, he would be an insane support engineer.

He managed to finish his entire bowl of soup in the time it took you to explain, and housed another two slices of buttered bread with the sort of alacrity you’d only ever seen in pro heroes and professional athletes, making you smile while you spoke.

His spoon clinked softly against the edge of the bowl as he set them aside on the coffee table, and he hooked his chin over your knees as you finished explaining. In the setting sun from your windows he looked especially lovely, the kind, angular planes of his face brushed in gold, softening the spots of his freckles.

His eyes were especially bright, the way they always were when something in particular had caught his interest, and he smiled at you again over the tops of your knee caps.

“I admire how smart you are,” he told you, in the simple, straightforward way he always gave out compliments. It was like a shot to the heart every time, and you could feel your face warm with the praise even after years of receiving similar compliments.

You reflexively flapped a dismissive hand. “Not smart enough to have internalized it all! I have mostly been falling asleep to it,” you promised him.

He tilted his head, a green curl falling into his eyes. “I know you won’t have a problem when you’re awake.”

You shifted your legs with embarrassment, and a long fingered hand came up to cup the front of your thigh, as Izuku turned more fully towards you. You could feel the warm, hard planes of his chest against your shins, the line of his jumpsuit’s zipper pressing insistently just below your knee.

“Gotta try to impress you somehow,” you joked, your skin prickling as Izuku’s fingers absent-mindedly drew a pattern across your thigh. You could feel the heat of his hand through the thin material of the leggings you’d lounged around in all day, the chill finally chased away from his skin now that he’d come inside and warmed up.

“You do impress me,” he said in his soft, gentle tone. Which made your cheeks and nose burn hotter.

You knew you did, and the steady faith Izuku had in the people around him was one of your favorite things about him. It still made you feel like a middle schooler with a crush to think about, though, the intensity of your feelings too much for one body to handle.

“I will study hard to live up to your faith in me,” you promised, unable to help the goofy smile you knew you were giving him.

Izuku’s chin shifted against the tops of your knees, and he pressed his mouth to the knob of your left one, leaving a smiling kiss. “Tell me more?” he asked, fingers still sliding softly over your thigh.

“I’ll read it to you as I go, then,” you said, turning back to the brick of a tome, propping it up more firmly on your stomach as you adjusted yourself against the couch arm. Izuku’s eyes watched you over the top of the pages, that emerald gaze tracking your face closely.

“‘The algorithm works via a two-phase process: a prediction phase and an update phase’,” you began, trying to turn your attention away from Izuku and back to the text. “‘In the prediction phase, the Kalman filter produces estimates of the current state variables, including their uncertainties. Once the outcome of the next measurement (necessarily corrupted with some error, including random noise) is observed, these estimates are updated using a weighted average, with more weight given to estimates with greater certainty.’”

Izuku’s long fingers traced firmer lines across your thighs, almost like he was taking notes. He layered another kiss along the line of your knee, eyes glittering at you as you read.

“‘The algorithm is recursive,’” you continued, “‘It can operate in real time, using only the present input measurements and the state calculated previously and its uncertainty matrix; no additional past information is required.’”

You almost jumped as Izuku’s mouth trailed lower, into the space between your knees, leaving kisses along your inner thigh. His fingers gently pulled one thigh away to make space for him in between, and you cleared your throat, trying to return to the text at hand.

“‘Optimality of Kalman filtering assumes that errors have a normal–that is, Gaussian–distribution,’” you read on. “‘The following assumptions are made about random processes: Physical random phenomena may be thought of as due to primary random sources exciting dynamic systems. The primary sources are assumed to be independent gaussian random processes with zero mean; the dynamic systems will be linear.’”

Izuku let out a soft breath, insinuating himself further between your thighs. Your own breath came out a little uneven as he bent over you, mouth tracking dangerously towards the inseam of your leggings.

You paused, but Izuku fixed you with a look of his slightly-darkened eyes. “Please—keep reading,” he said, his tone a little lower than it had been a minute ago.

You swallowed in shocked understanding, skin tingling. You felt yourself nod, as Izuku’s fingers strayed to the waist of your pants, dipping below the band.

You let him slowly peel your leggings down, your underwear with them, adjusting as needed to make it easy for him, even as you tried to return your attention to your textbook.

“‘Regardless of Gaussianity, however, if the process and measurement covariances are known, then the Kalman filter is the best possible linear estimator in the minimum mean-square-error sense,’” you quoted, nearly squeaking when Izuku pressed his mouth to your hip, his curls tickling the skin of your belly. His hands gripped either side of your thighs, palms square and rough against your skin, and you tried not to shiver with the feeling.

“Um—‘Although there may be better nonlinear estimators’,” you said, then nearly jumped out of your skin when Izuku pressed his mouth to the core of you, only the strength of his grip stopping you from accidentally kicking him in surprise.

“Oh my g—uh! It—um—‘It is a common misconception perpetuated in the literature that the Kalman filter cannot be rigorously applied unless all noise processes are assumed to be Gaussian,’” you managed, before your cut off into a groan as Izuku layered a hot, sweet kiss over you, tongue dipping carefully between your folds. “Ah-–Izuku—”

Izuku petted a thumb gently over the top of your thigh to show he was listening, even as he swiped his tongue over you again, a long, firm stroke that had your thighs flexing in his hold. He laved over your clit, sucking ever so slightly, and your grip almost tore the edge of your textbooks as it tightened.

“Keep going,” he urged briefly, then did it again, punching a groan out of you.

“Extensions—oh—‘Extensions and generalizations of the method have also been developed, such as the extended Kalman filter and the unscented Kalman filter which work on nonlinear systems,’” you read on, voice shooting up nearly into a squeal when two of Izuku’s long, firm fingers pressed into you, as his mouth moved over you again.

“Ah! Oh my god—the—um, the basis—-” you said, breath growing short. Izuku’s fingers unerringly found the spot inside you that made you twist in his grip with the ease of long practice, and his jaw worked as he kissed you so shockingly filthily. You could feel something already starting to build up behind your navel, a fluttery lightness, an insatiable insistence on more.

“‘The basis a hidden Markov model—oh, fuck—such that the state space of the latent variables is continuous and all latent and observed variables have–ah!--Gaussian distributions,’’’ you recited, your voice tripping up further into a register that sounded more like begging than reading.

Izuku’s fingers worked you, long and thick and perfect inside you, as his tongue drew unrelenting circles around your clit. Stars seemed to spark in your vision, and your eyes squeezed shut, losing your place on the page as your hips flexed into his face. You felt suddenly very floaty and lightheaded, and not at all in a position to keep going.

Still, you tried to refocus your attention.

“‘K–Kalman filtering has been used successfully in—oh—multi-sensor fusion—ah, ah!--and distributed sensor networks–fuck, please, Izuku—to develop distributed or consensus Kalman f-filtering,’” you said, your tone nearly a cry.

Izuku groaned softly, sucking gently as his fingers curled inside you. It made your veins spark under your skin, your legs shaking in Izuku’s hands. You abandoned your grip on your book to seize the arm of the couch, clawing desperately at the fabric.

“Please, Izuku,” you cried, hips bucking towards his mouth.

The book tumbled off your stomach but you hardly noticed, gaze refocusing on the way his eyelashes fluttered as he licked you. His fingers played gently within you, a maddening press that was simultaneously too much and not enough, and his other hand came up to slide under your sweater, plucking gently at your nipple.

You lost yourself to the feeling—caught between the mind-melting curl of his fingers, the delicate suction of his mouth, and the careful pinch of your nipple. A delicious heat curled through you, waves of unbearable pleasure, and you could hear yourself babbling nonsense—garbled syllables of Izuku’s name, and every entreaty you could think of, a hundred thousands mores and oh pleases.

Izuku abandoned your nipple to pull you more firmly against him with a strong arm curled under your thigh, pressing you even harder into his mouth.

You muffled a scream in the sleeve of your sweater as he sucked you harder, tongue laving over you in loving strokes. Only his terrible strength held you down as you writhed beneath him, and then his fingers twisted in a way that had your vision whiting out—and you were suddenly thrown out over the edge of your pleasure.

Izuku licked you through it as you squirmed and begged and cried out his name, your climax seeming to last for eons.

You were panting hard when you finally slumped into the cushions of your couch, the ceiling seeming to swim in and out of focus before your eyes. When you gained enough control of your body again you looked down at Izuku, finding him watching you with a satisfied, almost shy curl to his mouth.

“You’re beautiful,” he told you, emerald gaze glittering with sincerity. “You’re so smart.”

Impossibly you felt your heart swell with even more love for him, and you seized his shoulder, dragging him up over you so you could kiss his mouth. The taste of yourself on him was embarrassing yet thrilling, and you petted a pleased hand through Izuku’s wild mess of curls as you kissed him.

“Well you are amazing,” you told him, swiping a thumb over his cheek fondly, smoothing over his freckles. A gorgeous watercolor of pink washed over his cheeks and nose at the proclamation, and you could hear his fingers flex in the cushion beside your head.

The sight of him flushed and waiting over you like another small something inside of you, like a pilot light, and you let your mouth pull into a wry grin.

“I hope you know I learned nothing though,” you said casually, your plan for your next steps already forming in your head. You let a hand trail carefully down Izuku’s flank, tracking towards his waist. “I think maybe I might need a few rounds for it to really sink in.”

Izuku’s ears went red against the green of his hair, and you felt your smile widen. “Maybe you could read it to me this time?” you asked, guiding him to roll under you, retrieving your book from the floor as you did so.

You settled yourself on the tops of Izuku’s thighs, feeling the hard press of him against your core, as you placed your textbook into his waiting hands.

Izuku’s answering smile was all the permission you needed. You directed him to start from the beginning of the chapter, and he did so in that soft, lilting tone of his you so loved. And then your fingers trailed up to the zipper at his collar.

It was time to return the favor—wholeheartedly.
